Given numbers are 491, 550, 644, 163

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(491, 550) = 270050

GCD(491, 550) = ( 491 x 550 ) / 270050

= 491 / 550

= 491

Step2:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

Step3:

LCM(1, 163) = 163

GCD(1, 163) = ( 1 x 163 ) / 163

= 1 / 163

= 1

So, Greatest Common Divisor of 491, 550, 644, 163 is 1
